- .ghci: -j1 → -j4 for parallel module compilation - scripts/compile-check: auto-detect high-RAM hosts (>16GB) and set GHCRTS="-A256m -M20g" to reduce GC pressure - devenv.nix: update comment only (GHCRTS still set at runtime) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

# IHP's flake module (flake.nix) provides the full devenv shell via
|
|
# `inputs.devenv.flakeModule`: Haskell toolchain, PostgreSQL, ghcid,
|
|
# and RunDevServer. This file satisfies devenv v2's file-presence
|
|
# requirement and adds project-specific overrides on top.
|
|
#
|
|
# Duplicates the settings from flake.nix devenv.shells.default so they
|
|
# are applied under both devenv v1 (flake path) and devenv v2 (this file).
